An Empirical Study of Primary School Students'Statistical Reasoning Performance
The development of primary school students'statistical reasoning ability helps to promote students to develop a rational spirit of"speaking with data",which is in line with the literacy requirements of modern citizens in the era of big data.In this regard,a mixed research method is adopted.Taking 322 sixth-grade students from an ordinary public primary school as the research participants,the performance assessment is carried out based on the rubric of statistical reasoning ability.The current study depicts the overall performance and typical performance characteristics of students'statistical reasoning.The results show that:in terms of overall performance,nearly 90%of the sixth-grade students'statistical reasoning is at the Uni-structural level and Multi-structure level,and more than 50%of the students are at the Uni-structural level;a few students are still at the Pre-structure level,and very few can reach the Relational level.In terms of specific performance characteristics:86.0%of sixth graders can infer information beyond the data;90.1%of sixth graders can use data as evidence to preliminarily explain the inference;32.1%of them could really reflect on the uncertainty of the inference;and on the three indicators,students have different answering strategies and learning myths.As a result,by realizing the organic unity of the assessment framework,test items,and scoring standards,an assessment system for statistical reasoning ability is constructed,which reveals the reasoning cognitive process in the"statistics"area.The application provides a foundation for promoting the development of students'statistical reasoning ability and the cultivation of data awareness and reasoning awareness.
